Really nice looking game! The take on the theme was cool and I could totally see it grow into a full blown game. The tutorial was really well explained and the pictures helped a lot.
I personally solved the bug in level 3 by placing the reverse arrow just below the right pot.
I felt that the start of each level was a bit abrupt and I couldn't react to what was happening so I would always lose in my first try. Maybe waiting a bit before starting the level can help the player to make a plan and try to predict what's going to happen instead of watching it instantly.
Really cool game!
